make HI options as in Run 2

minimal fix for ATR-28062 - remove EnableHI specific options from the trigger config and always use BeamLine perigeeExpression in the trigger

ATR-26732

cc @tstreble - it can be done simpler by moving the base methods to use ActiveConfig but I chose to do the simplest to minimize iterations needed this week - I'll update it when I'm back to work
